kW to erg/s

kilowatt

• Definition: A kilowatt is a unit of power equal to one thousand watts. It is commonly used to measure the output of engines and the power consumption of electrical devices.

• Symbol: The symbol for kilowatt is kW.

• Usage: Kilowatts are often used in residential and commercial settings to indicate the power usage of appliances, heating systems, and other electrical devices.

erg per second

• Definition: An erg per second is a unit of power in the centimeter-gram-second (CGS) system. It is defined as the amount of energy transferred or converted per unit of time, specifically one erg per second.

• Symbol: The symbol for erg per second is erg/s.

• Usage: Ergs per second are typically used in scientific contexts, especially in physics and engineering, to quantify energy transfer or power in smaller systems.

Origin of the kilowatt

• The kilowatt originated from the watt, which is the SI unit of power named after Scottish inventor James Watt. The kilowatt was introduced to express larger quantities of power in a more manageable way, particularly in electrical engineering and energy consumption.

Origin of the erg per second

• The erg is a unit of energy in the CGS system, developed in the 19th century. The term “erg” comes from the Greek word “ergon,” meaning work. The erg per second as a measure of power emerged as scientists needed a unit to quantify energy transfer in various physical processes.
